PUMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 256,125, dated Aprilrll, 1882.

Application filed January 18, 1882.

To all whom it may concern:

Be it known that I, HENRY CLAYTON, of Dayton, in the county of Montgomery and State of Ohio, have invented certain Improvements in Pump Attachments, of which the following is a specification.

My invention consists in a detachable strainer "attachment of improved construction for pump-spouts, composed of a ring or band fitted to the end of the spout and provided with projecting lugs, and a cap or ring notched to look over said lugs and provided with a strainer, as hereinafter more fully set forth, and in providing the attachment with a valve for the discharge of sediment, 860., as will be explained.

In the accompanying drawings, Figure 1 represents a perspective view of a pump-spout with my improved attachment applied; Fig. 2, a view with the strainer-cap detached, and Fig. 3 a vertical transverse section of the attachment.

The object of my invention is to provide a cheap and simple attachment which may be applied to the spouts of pumps in common use to prevent the escape of sediment or foreign matters of any kind from the spout to the receiving-vessel placed beneath it. With this end in view I construct the device as shown in the drawing, in which- A represents a pump-spout; B, a ring or band, secured thereon by screws or otherwise and C, a cap, provided with a strainer, a, of wire-gauze or other suitable material, and having notches b to receive and-lock around logs or projections cforined on the band B. As more clearly shown in Fig. 3, the band B is formed with an internal radial flange or plate, d, to fit against the end of the pump-spout, and perforated to receive the fastening-screws e, as shown. It is also preferably constructed to project in rear of said flange, as shown in said figure, in order that it may encircle and protect the end of the spout.

The cap 0 consists merely of an annular metal band, preferably having an inwardlyturned flange, f, to which the straining material is secured by soldering, by a wire or metal ring pressed in behind it, or in any other usual and convenient way. The cap is formed, as

above stated, with notches or slots b, which are (No model.)

shown of L shape, but which may be curved or inclined, said notches being made to permit the cap 0 to be pressed upon the band D until the edge of the cap passes the lugs or projections 6, \vhen,'by turning the cap, it is caused to lock fast upon the band, as shown in Fig. 1.

For the purpose of removing any sediment which may collect within the spout or behind the strainer, the band is furnished with an outlet-valve, D, which is normally held closed by a spring, g, but which is provided with a thumb-piece or tail, h, by which it may be conveniently'operated. When, therefore, sediment collects, it is only necessary to press upon the thumb-piece h and operate the pump for a moment, when all depositwill be washed out.

Should any injury occur to the strainer, or should it be desired at any time to remove it from the spout, it is only necessary to turn the cap 0 and draw it off.

It will be seen that by reason of the plate or flange d the ring or band B, and consequeutly the entire attachment, may beapplied to pump-spouts of various sizes; and it will also be observed that the strainer-surface a is considerably larger than the opening in the plate or flange d, and consequently that afree outlet for the wateris afforded, the larger area compensating for the retarding tendency of the strainer.

I am aware that a strainer has heretofore been applied to pump-spouts and provided with a trap or valve to catch and retain frogs, 830., as well as foreign matters; but I am not aware that any one has ever before constructed such a device as herein set forth, or that a vided with lugs 0r projections, and the cap 0-, 4.
